I cleaned the condensate pans and drain lines and ran hot water to flush the debris and to check for proper drainage and condensate pump operation. I replaced the air filter for unit #1 with one provided by the customer, unit #2 was still very clean. I operated the units on second stage cooling and vs 100% cooling mode. Both units are cooling with 20+ degrees across the evaporator coils. I checked the electrical wiring and electrical systems, all are within specification. Both units are operating normal. I also ran the radiant floor heat to make sure it would operate because the customer was concerned that it was not working.
I recommend adding a hard start kit to unit #2 to help the compressor start much easier. I gave the customer an estimate.

Upon arrival I was told that master bedroom mini split AHU was making noises at night. Ran heat at max capacity and removed front panel. Could not really recreate noises. Customer sent me video that he took of noise unit is making. He informed me that it is similar to a pot boiling. Verified noise is not from pins popping on coil bracket. Can only speculate that it may be possible for air or contaminants to be in refrigerant lines because noise is coming from the middle of coil. Alex please watch/listen to video uploaded. Customer said he will continue to run system and see if noises continue because it is not every night.

Routed condensate pump drain line up and over to drain into the washer can. I verified proper operation without leaks. I also fixed a leak on the furnace drain line.

Upon arrival I was told that system was giving communication error to AHU. Called for heat and system didnâ€™t give fault, running normally. Found condensate was problem. Vinyl tubing going outside was freezing or covered with snow and wouldnâ€™t remove condensation. Removed power from pump and also removed safety wire and found same fault as recorded before. Found we had already run vinyl tubing to sump pump. Switched tubing so condensation runs into sump. Tested. Unit operating normal. Customer left before finishing so they did not sign invoice, only paid for service.

Upon arrival I was told that Hydronic System wasnâ€™t heating properly. During diagnostics customer turned heat on at both hydronic zones. Taco zone control getting signal and closing contacts. 120v going to both circ pumps but #2 not running. Switched from med speed to high speed and pump started running. Amp draw is very high, almost double the rated specs. Circ pump #1 at .51 amps while circ pump #2 at 1.01 amps. Spoke to Alex and he informed me that we did not install the Hydronic system. Quoting customer to replace 3 speed Grundfos Pump Type UPS15-58FC. Customer also Explained that unit 2 fan will run in heat mode but system is hydronic heat only. Went into thermostat settings and found airflow set to 500cfm when heat on. Turned off and tested hydronic settings. Unit operating normal at this time. Customer is going to speak to builder and plumber about who installed Hydronic system. Quoted customer to replace pump but she will get back to us. Per Alex, fee for today is waived.
